Aircon Leaking Water in Punggol
First, switch the unit off — every minute it runs, more condensation is being made with nowhere to go. An aircon leaking water looks alarming (and your wall paint agrees), but the mechanism is mundane: your aircon produces water constantly by design, and something in its exit route is blocked or broken. In Punggol flats the fix is usually a drainage clear-out, not a major repair. Here's the full picture.
Where the water comes from
Cooling air means condensing its moisture — a hard-working unit in Singapore's humidity pulls litres out of the air daily. All of it lands in a tray under the coil and exits through a drain pipe to the outside. Leaks happen when this plumbing fails: the tray overflows, and the overflow finds your wall, your curtains, or your bed. So the diagnostic question is never 'why is there water' — it's 'why isn't the water leaving'.
The four usual blockages, worst-first
One: a clogged drain line — dust and slime build until water backs up. This is the leading cause by far, and it's cleared as part of a $40 general service. Two: a fouled coil shedding gunk into the tray faster than the drain can cope — that pairs the drainage clear with a $90 chemical wash so the source is fixed, not just the symptom. Three: ice on the coil (from dirt-choked airflow or low gas) melting in sheets when the unit stops — the leak is secondary, the icing is the real issue. Four, least common: a cracked tray or a drain pipe that's lost its downward slope, which is a repair — $50 diagnosis, waived if you proceed.
How urgent is a leaking aircon?
The unit itself isn't in danger, but your flat is, mildly: water tracking down a wall stains paint, warps laminate and can reach power points below. Sensible urgency looks like: unit off, towel down, book within a day or two. Escalate to today if water is near electrical outlets, coming through a false ceiling, or dripping into a neighbour's territory below your ledge. What doesn't work is running the unit anyway and emptying containers — the blockage only grows.
What the visit looks like and what you'll pay
The technician confirms the water path, clears and flushes the drain line, checks the tray and pipe slope, and inspects the coil to judge whether it's feeding the clog. Most Punggol leaks close out at $40 (drainage cleared during general service) or $130 total ($90 chemical wash where the coil is the root cause — the drain flush is included in the wash). Damaged trays or re-sloped piping get a fixed quote after the $50 diagnosis. You'll see photos of the cleared drainage before payment, which happens after the work — PayNow or cash.
Frequently asked questions
Why does my aircon leak only at night?
Night is when it works hardest and longest — bedroom units run for hours, condensation production peaks, and a partial blockage that keeps up during a two-hour evening session gets overwhelmed by 3am. A partially clogged drain leaks at night first, then eventually all the time. Same fix either way: clear the line.
Is a leaking aircon dangerous to keep using?
The main risks are to your flat rather than the machine — stained walls, damaged flooring, and water near sockets. If ice is involved, continued running also strains the system. Off until fixed is the right call; the fix itself is usually same-week and inexpensive.
Can I unclog the aircon drain pipe myself?
The safe DIY stops at switching off and emptying/wiping the visible tray area if you can reach it. The clog usually sits deeper in the line where household tools don't reach, and poking at it can shift the pipe's slope and worsen things. A proper flush is part of a $40 service — it's cheap enough not to gamble.
The leak came back weeks after another company fixed it. Why?
Almost certainly the drain was cleared but the fouled coil feeding it wasn't — the slime rebuilds and the clog returns. That's the case for a $90 chemical wash: it cleans the source and flushes the line in one treatment. Our per-unit history also means a repeat visit starts from what was already done, not from zero.
